In Norway 1 Claim.

The present invention relates t a locking device for toe irons in skibindings and the object of the invention is partly to obtain a simple and safe device of this kind and partly to obtain a device which may be produced and sold at a low price.

According to the invention toe ears are used the horizontal parts of which are in a known way provided with rectangular openings having toothed edges coacting with a locking disc with countersunk fastening and locking parts. The main feature of the invention consists in a special construction of such toothed and countersunk parts in order to obtain a safer fastening than in previous constructions in which the locking teeth were produced by deforming the material along the conical sides, such locking teeth being produced along the outermost sides of the countersunk parts toward the ends of the same. Such locking teeth however, had an insecure connection to the parts which were to be locked by the same. This drawback is overcome by the present invention according to which the locking teeth are made free by slitting the material at the toothed spot. Teeth produced in this manner cause an effective fastening to the toe irons and in this manner accurately fix the relative position of the parts.

'I'he invention is illustrated in the enclosed 30 drawing in which:

Fig. 1 shows a toe iron provided with a locking disc seen from above.

November 24, 1934 Fig'. 2 is a perspective View of a fractional part of the locking disc seen from below.

Fig. 3 is a sectional View upon the line III-III of Fig. 1.

In the drawing, numerals I and 2 designate the toe irons and 3 a locking disc placed above the horizontal parts of the toe irons, 'I'he horizontal parts of the toe irons are provided with rectangular openings having teeth 4, 5, 6, 'l along the edges next to the front and rear edges of the toe irons. Such openings are adapted to engage with countersunk parts 8 of the locking disc 3, which parts are provided with screw holes for the fastening screws 9 and the sides of the countersunk parts 8 coact with the toothed sides of the rectangular openings of the toe irons. For this reason said parts 8 are slit open as shown at I0 and provided with a number of teeth Il adapted for engaging said toothed edges of the toe iron openings for locking purpose.

I claim:

In ski-bindings the combination with a pair of divided toe irons, substantially rectangular openings being provided in the horizontal parts of said irons, teeth along an edge of the openings, a locking disc having bulging portions with screw holes, said portions being slit on the sides turning toward the teeth of the toe iron-openings and provided with locking teeth adapted for locking with the teeth of the toe iron-openings in the same horizontal plane.
